When you upload an image using Media Uploader, WordPress generates multiple copies/thumbnails of that image. By default, WordPress generates 4 thumbnails-

  • Thumbnail
  • Medium
  • Medium-large
  • Large

But along with this, theme and plugin developers can register their own thumbnails. Although they may be on purpose, but sometimes they remain unused.

Think about it, unnecessary additional images are eating up your server space and slowing down your site!

Sounds like a problem? What is the solution then?
This is where our plugin comes into the picture. Just install the plugin and choose which of the image sizes you want to prevent from generating.

  • Works with any plugin and theme.
  • WooCommerce compatible.
  • Multisite compatible.
  • Super easy to install and configure.
  • It’s free and always will be.

  • simple and useful in many ways

    I had to rethink the option of deleting my extra images or not. After some research I had chosen to change my function.php code instead of using a plugin. But this ImageSize has helped me to check what strings where actually the ones to modify. I have now uninstalled it, but when I tested it worked smoothly. It’s very useful if you know that you will never need extra images… in my case I needed to do a custom setting so I’m not using it anymore but, as I said, ImageSize is simple and effective.

  • Works great!

    I have this on 5 different installations now. I used it along with Force Regenerate Thumbnails to get rid of lots of unneeded redundant images that were taking up my storage quota. Use this plugin first to specify which sizes you want to generate, then run Force Regenerate Thumbnails to delete the redundant sizes. I had 9 additional resizes being created by WordPress and my theme! That’s a lot of wasted space. Just be sure not to get rid of sizes that are actually being used for something!

  • Excellent. Just what I needed.

    Excellent. Something that should exist years ago, finally here.

  • Best and only working plugin!

    It perfectly works on all versions of WP. It does what it says.
    Stops generating unnecessary image sizes, so save spaces and prevent crowded files.
    Best of the best.

  • Essential plugin

    You are a hero. The resizing of images by WordPress is borderline moronic. Increasing uploaded image sizes (in kb) almost tenfold, sometimes!

    This plugin is a must-have for optimizing loading speeds.

  • most useful plugin i ever tested

    this must be the most useful plugin i ever tested in wordpress, without this i couldn’t even bare to use wordpress. this save me from the hideous plague of duplicated, unwanted and ridiculous auto generated thumbs. thanks a lot 🙂

  • Stop generating thumbnails

    You can combine this plugin with Photon’s Jetpack, thumbnails are created on-the-fly on the jetpack server.

  • It works! but…

    I’ve just used this plugin, and it cleaned about 80% useless files, so MARVELOUS!! However, a part of thumbnails were resized (ex: from 300×179 to 300×180), so that some articles couldn’t read them, and I must edit the articles manually. It’s a very good plugin, KEEP GOING and IMPROVE IT!
